Disagree! While not all entries are perfect, and Wikipedia as a whole can be pretty flawed (who is writing these entries?), there are some entries that are really well researched and written. There’s a movement w/librarians right now to take a more active role in researching Wikipedia articles -- in fact, there’s a Wikipedia Edit-a-thon at this year’s annual librarian conference.

Hi:
The whole concept of Wikipedia is flagged, for one part, it is not allowed to “copy and paste” articles but for other part, to put “own material” is not allowed. So, most articles live in a limbo of “half copy and half self invention”. And if we add the fact that an editor could be any person, no matter if it is an expert or kid.
